Young's Travels in France, have touched social and political history; but for the most part, authorship of agricultural travel is yet undeveloped. The spirit of scientific inquiry must now be taken into this field, and all earth-conquest must be compared and the results be given to the people that work.
Crustacean Farming: Ranching and Culture, Second edition. John F. Wickins and Daniel O'C Lee. The second edition of an extremely well-received book, Crustacean Farming, deals with all cultivated crustaceans of commercial significance, shrimp, prawns, crayfish, lobsters, crabs, and spiny lobsters, and examines the criteria by which both the feasibility and desirability of farming proposals are assessed. The characteristics and production methods of farmed and candidate crustacean species are described in sufficient detail to enable areas of profitable involvement to be distinguished form other opportunities presenting only very high risks and possibilities for serious loss. Coverage extends right from broodstock acquisition and management through to the operation of hatcheries, nurseries and on-growing units to key aspects of processing and marketing. New to this second edition are ranching and re-stocking operations together with the culture of ornamental shrimp and small crustaceans used as live food in fish and shellfish hatcheries. The sections on crustacean diseases, genetics and nutrition have been extended in the light of recent research advances. Examples of investment and operating costs of the different culture options are compared and an analysis of current trends in world crustacean markets is presented to assist in economic and financial appraisal. Special consideration is given to the place of crustacean farming within the economics of developing nations in relation to social and environmental impact in order to promote awareness of the wider implications of global developments. The consequences of recent research and technical developments are considered, together with concerns over genetic and animal welfare issues. Specific areas where further advances in technology are needed to improve the reliability or productivity of farming systems are highlighted. This important book is a vital tool and reference work for all those involved with crustacean farming worldwide.
Molybdenum (Mo) deficiencies in field-grown plants were first recorded more than 50 years ago and this book condenses all the information currently available on the subject of molybdenum as it relates to soils, crops and livestock. The book reviews our knowledge of the chemistry and mineralogy of Mo, the extraction of available Mo from various soils, the various analytical methods of determining Mo in soils and plants, the biochemical role of Mo in crop production, the technology and application of Mo fertilizers to crops, the response to Mo of various temperate and tropical crops, Mo deficiency and toxicity in various plant species, the interaction of Mo with other plant nutrients, and the distribution of Mo within the plant. Factors affecting the availability of soil Mo to plants and Mo status in the semi-arid and sub-humid tropics are also discussed.
Rev. Thos. Owen published at don in 1803, is at once inadequate scarce. For this reason the pres editor has ventured to translate the Latin (and to annotate from.
Primorse McConnell's The Agricultural Notebook: 18th Edition is a collection of articles about important areas of discussion in agriculture, all of which written by experts from different related fields. The book is divided into four parts. Part 1 deals with concepts related to crop production such as soil its classifications, mineral components, and physical properties; the benefits, problem diagnosis and system layout, and maintenance of drainage systems; the physiology, nutrition, and kinds of crops; and related problems such as weeds and diseases and their control. Part 2 is concerned with animals important in agriculture and deals with topics such as livestock feeds and the breeding, management, and meat production of cattle, sheep, goats, pigs, and poultry. Part 3 discusses farm equipment such as tractors, crop sprayers, and planting machines. Part 4 tackles the management of the farming business and its staff; it also tackles laws related to agriculture and the health and safety of its personnel. The monograph is recommended for entrepreneurs in the field of agriculture, as well as those concerned in its studies and improvement.
The commentary has been thoroughly overhauled. In its original form it owed a great deal to the edition of Andresen The debt remains, and, indeed, is increased by the use that has been made of the later work of that veteran scholar. Some unimportant notes have been cut out references to parallel passages (often less necessary now than they were in 1898) have been considerably reduced; the shorter notes have been largely re-worded or altered, or both most or all of the more important notes have been re-written; and new notes have been added. The changes are thus great, but the total bulk of the volume is hardly smaller. In apology one must plead the desire to furnish students of what F urneaux called a unique specimen of ancient literature and one of exceptional interest to Ehglish readers with an edition which should not only discuss critically the numerous difficulties of text and interpretation, but also provide a bird's-eye view of the results of historical and archaeological inquiry. The introductions and appendixes deal rather fully with a wide range of subjects, and if the last two appendixes travel somewhat outside the ordinary scope of a historical edition, they will be welcomed for their intrinsic value. My thanks are due to the representa tiyes of the Clarendon Press for the breadth of view which they have shown in this respect and for the liberal compensation which they have allowed, in the shape of maps and illustrations, for their inability to print the commentary below the text.
